What's the longest you spent stationary?

Nobody on Shap? Twice on Shap overnight in the sixties, second one a bloke in a chauffeur
-driven Bentley shared his cocktail cabinet, and once for two days on Beatock, when my car broke down, and then it snowed before my mate could get to me, so we were both stuck!
Hell, I’ve just realised that they were almost 60 years ago!
